Determination of Trace EDTA by Kinetic-Spectrophotometry Inhibition in Murexide-KIO_4 System;
紫脲酸铵-KIO_4体系阻抑动力学光度法测定痕量EDTA
The solution was then titrated with EDTA using murexide as an indicator.
选用络合能力很强的w=5％的NaCN溶液络合浸锌液中全部的金属离子,待全部金属离子完全络合后选用w=4％的释放剂甲醛释放锌离子,然后采用紫脲酸铵作为指示剂,用EDTA滴定。
The content of nickel in sample was determined with murexide as indicator, EDTA standard solution as titrant under the condition of pH value 9-10.
试样经加热分解后用盐酸溶解,在pH值为9~10时,以紫脲酸铵为指示剂,用EDTA标准溶液滴定镍量。
This is a new adsorption phenomenon showing the complexity of murexide adsorption.
这是一种新的吸附现象,表明了紫脲酸铵吸附过程的复杂性,对其机理进行了讨论.
